The less the self is concerned with worldly matters, the greater the soul’s receptivity to messages and guidance via the heart.
People who excel in the material world are unlikely to be able to give sufficient attention to the exploration of the inner subtler realms. Love, trust and absorption in the outer world may harden the heart and hinder spiritual progress. Worldly people are often given a chance to reflect upon meanings and higher purposes through failures and difficulties, but their persistent mental habits and egos block inner openings and a balanced life.
When you concern yourself with what does not concern you, you will miss giving attention to what should concern you and is important for your evolvement.
By Shaykh Fadhlalla Haeri from the book “Witnessing Perfection”
